| Question | Answer |
|---|---|
| a measure of how hot (or cold) something is; specifically, a measure of the average kinetic energy of the particles in an object | temperature |
| an instrument that measures and indicates temperature | thermometer |
| the temperature at which molecular energy is at a minimum (0 K or -273 degrees C) | absolute zero |
| the energy transferred between objects that are at different temperatures | heat |
| the transfer of energy as heat through a material | thermal conduction |
| the movement of matter due to differences in density that are caused by temperature variations | convection |
| any movement of matter that results from differences in density; may be vertical, circular, or cyclical | convection current |
| the energy that is transferred as electromagnetic waves, such as visible light and infrared waves | radiation |
| the quantity of heat required to raise a unit mass of homogeneous material 1 K or 1 degree Celsius in a specified way given constant pressure and volume | specific heat |
| a measure of the randomness or disorder of a system | entropy |
| a machine that transforms heat into mechanical energy or work | heat engine |
